I can't get KillBill 2 to play on my PC. I bought it last week and it wouldn't play in my PC, so after I searched the forum I took it back and got another one. This one doesn't play either. I have hundreds of DVD's that will, this one is being difficult. 1300MHz Pentium 4 512MB RAM Sony DRU-500AX DVD Rewritable Drive PowerDVD DVD Region + CSS Free DVD Decrypter DVD Shrink Nero 6 Ultra Edition Please Help!!
